First Green Lesson Plan 9b (Age 11-14) - How fast does the water flow

Introduction
Greenkeepers use maths on the golf course in many ways. They may need to know how fast the water in a stream is flowing.

In this session students will calculate the speed the water flows in a stream by timing how long a tennis ball travels along a set distance in the water. (Please note that students in the UK work in metric rather than imperial units.)

Student Learning Objectives
By the end of the session students will be able to:

• carry out an experiment to calculate the speed water flows in a stream
• explain that reliable results are those that can be reproduced consistently using the same method
• state that speed is measured in metres per second (m/s)
• convert the units for speed from metres per second to kilometres per second and metres per minute
